Abstract

Sistem jaringan drainase pada DPS Senapelan 1 masih belum memadai, sehingga jaringan yang ada tidak berfungsi maksimal. Penelitian banjir pada drainase di DPS Senapelan 1 bertujuan untuk mengevaluasi kemampuan kapasitas saluran yang ada dan menentukan alternatif penanganan masalah banjir. Penelusuran banjir dilakukan dengan menganalisa masing-masing kapasitas saluran dan membandingkanya dengan debit rencana yang dihitung dengan metode Rasional. Analisa kapasitas sungai Senapelan 1 dihitung dengan prinsip hidrolika menggunakan software HEC-RAS. Berdasarkan luas DPS, maka input hujan sebagai boundary condition dilakukan pada kala ulang 25 tahun. Analisis profil dilakukan pada kondisi eksisting dan pada kondisi rencana. Hasil penelitian saluran sekunder menunjukan bahwa daerah yang mengalami banjir adalah jalan kenanga, jalan Melati, jalan Cempaka, jalan Teratai dan jalan Seroja. Upaya penanganan yang dilakukan adalah dengan melakukan pembesaran dimensi saluran dan pembersihan saluran. Simulasi HEC-RAS di sungai Senapelan 1 pada kondisi eksisting, dengan hujan kala ulang 25 tahun, terjadi banjir dengan ketinggian genangan bervariasi antara 0,10 m – 0,20 m. Penanganan yang dilakukan adalah dengan melakukan normalisasi sungai dan saluran drainase.

Abstract

The admiralty method is one of common method that used to predict tides. Tidal prediction with admiralty method is done using 15 days and 29 days tidal data. This research aims to compare the accurary of admiralty method’s result. Tidal data of Port C of Pelindo, Dumai has been analyzed using 29 days and 15 days admiralty method. The results of this research indicated that the results of tidal analysis using 29 days admiralty method generated the smallest RMSE (Root Mean Square Error) value of 44.36 cm, however 15 days admiralty method generated the smallest RMSE value of 70.39 m. So, the result of 29 days admiralty method tidal prediction is more accurate than 15 days admiralty method.

Abstract

Kusairi, M., Sutikno, S., Yusa, M., Hendri, A., Rinaldi, R. (2024). Analysis of peatland water balance in the peatland hydrological unit Pulau Rupat, Riau Province. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 649–658).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Peatlands are the largest place that can be used as water storage. Peatlands consist of 90% water and 10% organic matter, most of which is carbon. With a very large water content, water balance analysis is very appropriate to be used to determine the characteristics of PHU Pulau Rupat. Water balance analysis is a very important analysis to see the condition of the volume of water available spatially and temporally. This study aimed to analyze the condition of the water balance in PHU Pulau Rupat. The analysis is based on the condition of the water balance of each Sub PHU using the MONALAGA water balance model. Based on this method, it was found that PHU Pulau Rupat has two periods of deficit conditions each year. This condition is in accordance with the characteristics of the dry season in Riau Province. The difference between surplus and deficit was -80.46 million m3 in 2014, this condition is in accordance with the presence of 1,216 hotspots in sub PHU-2. The deficit month period that is prone to fires occurs in January to March, then in the period from June to August. Based on these conditions, it can be the basis for water management in controlling peatland fire disasters. So that the level of fire vulnerability in PHU Pulau Rupat can be reduced through collaboration between parties in dealing with deficit months.

Abstract

Peatlands play a crucial role in the global carbon cycle, water regulation, biodiversity conservation, research, education, and recreation. Peat thickness and groundwater level (GWL) are key parameters for optimizing these peatland functions; therefore, mapping peat thickness and GWL quickly, accurately, and cost-effectively is essential. This study applied a geophysical survey using a portable electromagnetic instrument to estimate peat thickness and GWL. The instrument, which is simple to operate and wirelessly connected to a mobile phone, enables rapid measurement and visualization of subsurface resistivity. A research site in Indragiri Hilir Regency, Riau Province, Indonesia, was picked up as an experiment site to test the instrument. Three transects with measurement path lengths of 100 m each and a distance of about 1.4 km each were designed for the experiment. To validate the resistivity data against subsurface stratigraphy, core sampling was conducted at three points along each transect. The results demonstrated that the electromagnetic method effectively identified the interface between peat soil and the underlying marine clay. Analysis revealed that the resistivity values for unsaturated peat, saturated peat, and saturated clay were 68-81 ohm m, 75-96 ohm m, and 82-115 ohm m, respectively. These findings suggest that GWL mapping and peat stratigraphy characterization can be accurately achieved using this method.

Abstract

Changes in river mouth section capacity caused by instability of river mouth stability would influence flow conditions in upstream estuaries, as impacted by unsmooth drainage of river flow. Section river capacity and mouth river stability of Siak River would be evaluated by the output of tidal prism at the estuary. The tidal prism was predicted by Hecras software. Input data for hydrodynamic simulation consisted of river geometric data, river bed condition, and boundary condition (discharge and water level). The maximum daily rainfall data and Siak’s catchment parameter could predict flood discharge. Longshore sediment transport netto data could be calculated using wave depth data, wave velocity data and direction of wave around the mouth river. The results of the tidal prism calculation show that the existing cross-sectional area of the mouth of the Siak River estuary can only drain the volume of water due to discharge and tides in the 2-year return period (Amin = 3,115 m2 < A ada = 3,225 m2), while for discharge with other return periods, the capacity of the cross-section river is not sufficient. The excess discharge will flow upstream as a backwater. Siak River mouth stability is still relatively good and stable, with a stability number (S) of more than 388,0 (requirement: S > 150). The start of the backwater effect at KM+220 (60 km from the mouth of the river) caused a significant change in water level (0.94 m) due to the damming of the flow caused by the influence of tides and the bifurcation node of the river (delta).
